Kelleher said he wasn't surprised to see both the New Zealand dollar and the Australian dollar rise after Bank of England governor Mark Carney signalled it may be necessary to remove some of the bank's monetary stimulus, suggesting interest rates could be raised as British economic growth picks up, while policymakers at the Bank of Canada suggested they might move to tighten rates as early as July.
"The market is now questioning whether the RBA and the RBNZ might have to go as well," despite efforts by both central banks to signal rates would be on hold for quite some time, he said.
The kiwi fell against the British pound overnight after Carney's comments but was little changed in Asia and was trading at 56.46 British pence from 56.50 British pence as at 8am in Wellington and from 56.77 pence late yesterday.
It was also largely unchanged against the euro after the market shrugged off attempts by European Central Bank president Mario Draghi to tone down his prior statement when he hinted the ECB might start winding down its stimulus. "The market is largely ignoring Draghi, in particular after Carney and the Bank of Canada," said Kelleher. "They don't believe him in the slightest."
The kiwi was trading at 64.15 euro cents from 64.11 cents late yesterday.
Looking ahead, Kelleher said markets will be watching for US core personal consumption expenditures (PCE) index data, Federal Reserve Chair Janet Yellen's preferred measure of inflation.
The local currency slipped to 95.52 Australian cents from 95.72 cents late yesterday and rose to 82.10 yen from 81.59 yen. The kiwi gained to 4.9588 yuan from 4.9487 yuan.
New Zealand's two-year swap rate rose 2 basis points to 2.26 percent while the 10-year swap rate rose 4 basis points to 3.24 percent.
